The people need the preparation of a high tide hazard map that seeks refuge from high tide flood, induction as the soft measure, that adds the upgrade of infrastructure. In recent years, people are requesting to reduce human damage from the high tide disaster more. However, great time is needed to the upgrading of a security infrastructure. Constructing the high tide flood model that considered the lay of the land characteristic of the low plain of the coast area that is weak to a high tide disaster in this research.
We carried out the method examination that is able to do the high tide flood prediction close to a real phenomenon more. Although similarly river of flood calculation uses two-dimensional unsteady flow models, a model examined the model construction by finite element method. Furthermore, the model that takes the rainfall to the flood field was made, as it is possible in the problem of the inner drainage in the low ground that was enclosed in a high tide embankment and also river embankment.
